DARCY A. YOUNG, OF MILFORD, MASSACHUSETTS, ASSIGNOR T9 AMERICAN WRINGER.COMPANY, OF WOONSOCKET, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.

WRINGER.

To all whom 'z't may concern:

Be it known that I, DARCY A. Yocxo, a citizen of the United States,residing at Milford, in the county of lVorcester and State ofMassachusetts, have invented a new and useful Improvement in lVringers,of which the following is a specification.

This invention relates to certain new and useful improvements in awringer and more particularly' to attachments for the wringer frame toincrease the efficiency and safety of the machine.

The principal object of the invention is to provide a wringer with asafety device for relieving the wringer rolls of pressure in anemergency, and a further object is to mount an improved guide board onthe wooden frame of the wringer.

Other objects will appear as the description progresses, and thosefeatures on which protection is desired will be defined in the appendedclaims.

In the drawings:

Figure 1 is a front elevation of a wringcr embodying the presentinvention.

Fig. 2 is a top plan view and-Fig. 3 is an end elevation thereof.

Fig. 4 is a fragmental view depicting the safety device in verticalsection.

Fig. 5 is a top plan view of the safety device operative, and

Fig. 6 is a lengthwise section therethrough on line 66 of Fig. 5.

More specifically referring to the drawings, the numerals 1 designatethe end uprights of the wooden wringer frame, 2 the squeeze rolls whichhave their end trunnions journaled in bearings 3 disposed in thevertical guideways 4 of the uprights, and 5 the intergearing between therolls for transmitting motion from one to the other as imparted theretoby a crank handle 6 or other motive power not shown.

Arranged on each side of the wringer frame is a guide board 7 preferablycast from aluminum with terminal right angular vertical brackets 8 toembrace the inside and front faces of the uprights 1. The brackets alsodefine side walls for the guide board to prevent the clothes from ridingoff the ends of the rolls. Braces 9 underliethe guide boards and notonly serve as a reinforcement to the frame but also to said guideboards.

Coiled springs 10 are seated on the upper Specification of LettersPatent.

Application filed April 28, 1919. Serial No. 293,283.

roll bearings 3 and housed within the guideways 4 and on each spring isa cap bearing 11. 'The upper ends of the frame uprights carry fittings12 having inturned lips 13 that overhang the cap bearings 11 and aredesigned to have the outer. ends of a pressure releasing or relievingbar 14 engage there beneath. This bar comprises jointed sections forbreaking upwardly which breaking action will withdraw the outer endsfroinbeneath lips 13 and thus release the springs to relieve the rollsfrom the pressure.

To hold this sectional folding bar in extended position, a locking lever15 is pivoted on the inner end of one section to swing over the adjacentend of the companion bar section and engage a keeper lug l6.

The locking lever is equipped with a pair of oppositely extendinghandles 17 one oneach side of the breakable bar and broadenedto'providea relatively large striking surface. Threaded through the outer ends ofthe'bar are screws 18 adjustable by the head wings 19 to vary theirpressure on the cap bearings and springs.

In practice should the clothing bunch between the rolls or an attendanthave his hand drawn in therebetween, it is only necessary to strike orpush' against either handle 17 which will swing the lock lever clear ofits keeper and permit the bar break ing upwardly under the influence ofthe' springs which breaking withdraws the bar terminals from beneath thelips 12. Thus, the springs are free to expand-and thereby relieve theupper roll from pressure.

The safety pressure relieving dev1ce is simple and efficient beingapplicable to any form of wringer, either manually or mechanicallyoperated. When the safety device is operated it removes all pressurefrom. the springs and rolls and when inoperatlve it functions as a bracefor the wrlnger frame.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1 1. In combination with a wringer frame andlips on the upper end of the frame, a pressure bar com osed of sections,the inner ends of which a ut each other, the outer ends of the sectionsbeing engageable beneath said lips, means to hingedly connect said innerends of the sections, a keeper lug formed on the upper face of onesection, a horizontally disposed lock member pivoted to move in ahorizontal plane and borne by the upper face of the other section andhaving a pair of oppositely disposed spaced handles arranged, one on andalong each side of the frame, and a catch centrally arranged in thespace between the handles and having a downwardly facing part receivingand operating over the keeper lug.

2. In combination with a wringer frame and lips on the upper end of theframe, a pressure bar composed of sections, the inner nd of which abuteach other, the outer ends of the sections being engageable beneath saidlips, means to hingedly connect said nmer ends of the sections, a keeperlug formed on the upper face of one section, a

' horizontally disposed lock member pivoted to move in a horizontalplane and borne by the upper face of the other section, said memberhaving a downwardly facing catch extendlng outwardly from an end thereofand engageable over the keeper lug, a handle extending outwardly from said end of the member and arranged alongside the keeper and spacedtherefrom,and a second handle extending outwardly from the opposite endof the member in a direction opposite to the first handle andsubstantially parallel thereto, the handles extending longitudinallyalong the frame sides, and having parts engaged with the respectiveopposite sides of the frame so as to limit swinging of the lock in bothdirections.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
